Many women show great interest in improving their fertility during their attempts to conceive. In this process, they adopt various dietary and other habits, such as consuming sunflower seeds, increasing omega-3 fatty acid intake, limiting alcohol consumption, staying in bed after sexual intercourse, and taking cough syrup, possibly due to its effects on cervical mucus (though there is no scientific evidence to support this).
However, it is important for them to know that not all herbs are suitable. As Anna Bohnengel, MS, RD, LD, founder of Fertility Nutritionist, points out: “Herbs can be used to treat hormonal imbalances that often cause fertility issues. However, while they can offer some benefits under the careful supervision of a doctor, they may also have potential side effects.”
Which herbs should be avoided when trying to conceive?
Specifically:
- Echinacea: Echinacea is well-known for its use in boosting the immune system. However, a previous study from 1999 highlighted that high concentrations of echinacea could harm both immature eggs and sperm.
- St John’s Wort: St. John’s Wort, also known as Hypericum, is used to treat depression. While it is recognized for its mental health benefits, there are concerns about its impact on fertility. Research shows that the active ingredients in St. John’s Wort may have toxic effects, as some animal studies have indicated that it may hinder conception by reducing sperm’s ability to penetrate the egg.
- Black Cohosh: Black Cohosh is a plant often used to maintain and treat normal hormonal balance. Studies have also shown that it is effective in reducing hot flashes, anxiety, and vaginal dryness during menopause. However, it is best avoided when trying to conceive.
- Pennyroyal: Pennyroyal, also known as wild mint, can help regulate menstrual flow in women with delayed periods. However, like many other herbs, Pennyroyal can also cause uterine contractions, so caution is advised when using it.
- Goldenseal: Goldenseal is a plant from the buttercup family with antibacterial properties and immune-boosting effects. While it may be used to improve fertility in women with Polycystic Ovary Syndrome (PCOS), it is not considered safe after conception due to the risk of causing uterine contractions, which can increase the risk of miscarriage. Therefore, it is recommended to avoid using it both when trying to conceive and during pregnancy.
